Appending JS to the HTML - javascript

I am trying to append my variables 'showName' and 'showDescription' to the 'results' div object. I have tried to add them in using 'innerHTML' but I just get the description shown. I have tried making additional divs to put INSIDE the 'results' div but that didn't work either.
I want the 'showName' to appear above the 'showDescription in the div.
I am challenging myself to not use JQuery so that is not a viable option.
code:
document.querySelector('.search').addEventListener('keypress', function(e){//On button click of enter, get the value of the search bar and concatanate it to the end of the url
if(e.key==='Enter'){
var query = document.getElementById('main').value;
var url = fetch("http://api.tvmaze.com/search/shows?q="+query) //use fetch to get the data from the url, THEN convert it to json THEN console.log the data.
.then(response => response.json())
.then(data => {
console.log(data)
var domObject = document.createElement('div')
domObject.id="myDiv";
domObject.style.width="800px";
domObject.style.height="5000px";
domObject.style.display="flex";
domObject.style.flexDirection="column";
domObject.style.margin="auto";
domObject.style.borderRadius="30px";
domObject.style.background="";
document.body.appendChild(domObject);
for (var i = 0; i < data.length; i++) { //for all the items returned, loop through each one and show the name of the show and the dsescription of the show.
var showName = data[i].show.name;
//console.log(showName);
var showDescription = data[i].show.summary
//console.log(showDescription);
var results = document.createElement('div')
results.id="myResults";
results.style.width="600px"
results.style.height="400px";
results.style.background="white";
results.style.margin="auto";
results.style.borderRadius="30px";
results.style.fontFamily="Poppins"
results.style.display="flex";
results.style.flexDirection="column";
results.innerHTML=showName;
results.innerHTML=showDescription;
document.getElementById("myDiv").appendChild(results);
}
})
}
});
document.querySelector('.search').addEventListener('keydown', function(o){
if(o.key==='Backspace'){
location.reload();
}
});
result of searching in 'car'

results.innerHTML = showName;
results.innerHTML = showDescription;
With this you are overwriting showName with showDescription.
What you need to do is concatenate with +=.
Also, it will be much easier to replace this:
domObject.style.width = "800px";
domObject.style.height = "5000px";
domObject.style.display = "flex";
domObject.style.flexDirection = "column";
domObject.style.margin = "auto";
domObject.style.borderRadius = "30px";
domObject.style.background = "";
with domObject.classList.add('some-class');
and CSS will be:
.some-class {
width: 800px;
height: 500px;
// etc...
}

Moved your code to a working example.
Note: because of authors styles, it is only possible to run snippet in fullscreen. =)
const dosearch = () => {
var query = document.getElementById('main').value;
var url = fetch("https://api.tvmaze.com/search/shows?q=" + query)
.then(response => response.json())
.then(data => {
const myDiv = document.getElementById("myDiv");
myDiv.innerHTML = ''; // <---- this is for testing
for (var i = 0; i < data.length; i++) {
var showName = data[i].show.name;
var showDescription = data[i].show.summary
var results = document.createElement('div');
results.className = 'myResults';
var header = document.createElement('h2');
header.innerHTML = showName;
results.appendChild(header);
var desc = document.createElement('div');
desc.innerHTML = showDescription;
results.appendChild(desc);
myDiv.appendChild(results);
}
});
}
document.querySelector('.search').addEventListener('keypress', function(e) {
if (e.key === 'Enter') {
dosearch();
}
});
#myDiv {
width: 800px;

Print data in javascript from json

I would like to print json policyUrl from every record in javascript and I mean policyUrl. if i try to print it console live server its work corectly but if I try to clg it in by loop its not working
Here is all data . https://github.com/neqts/jsonData
Help...
"use strict"
console.log(json)
const getNames = (obj) => Object.values(obj).map(el => el.name)
const purposesNames =getNames(json.purposes)
const vendorsNames = getNames(json.vendors)
const specialFeaturesNames =getNames(json.specialFeatures)
const specialPurposesNames = getNames(json.specialPurposes)
const stacksNames = getNames(json.stacks)
console.log(purposesNames,vendorsNames,specialFeaturesNames,specialPurposesNames,stacksNames)
var step;
for (step = 0; step < 972; step++) {
console.log(json.vendors[step].policyUrl)
}
console.log(json.vendors[1].policyUrl)
In your script.js replace your loop with the following:
Object.entries(json.vendors).forEach(vendor => console.log(vendor[1].policyUrl))
Your script is not working since json.vendors is not an array. You can change your json data to an array solution or you have to parse the data with Object.entries to an array.
for innerHTML, here is the updated script. let me know..
"use strict"
console.log(json)
const getNames = (obj) => Object.values(obj).map(el => el.name)
const purposesNames = getNames(json.purposes)
const vendorsNames = getNames(json.vendors)
const specialFeaturesNames = getNames(json.specialFeatures)
const specialPurposesNames = getNames(json.specialPurposes)
const stacksNames = getNames(json.stacks)
let outputArr = []
window.onload = function main() {
const add = document.createElement('div')
add.setAttribute("id", "demo");
const overall = document.createElement('div')
Object.entries(json.vendors).forEach(vendor => {
outputArr.push(vendor[1].policyUrl) + "<br>"
})
//console.log(outputArr)
overall.style.cssText = `
position: fixed;
z-index: 1000;
left: 0;
top: 0;
width: 100vw;
height: 100vh;
display: flex;
align-items: center;
justify-content: center;

`;
add.style.cssText = `
display: flex;
justify-content: center;
align-items: center;
width: 300px;
height: 400px;
background: white;
margin-left:150px
`;
add.textContent = "GDPR consent"
overall.appendChild(add);
//document.body.style.overflow="hidden"
document.body.appendChild(add);
//document.body.style.background = "url(https://www.hgsm.pl/wp-content/uploads/2017/03/Pattern-Blue-Dots-background-patterns-pattern-wallpapers-1920x1080.jpg)"
var final = document.getElementById("demo");
final.innerHTML = outputArr.join('<br>');

How to inject an id attribute to HTML with its value coming from a for loop using JavaScript?

const renderProgress = () => {
let qIndex = 0;
const lastQuestion = 20
const queryAllProgress = document.getElementsByClassName("query__all-progress");
const queryAllProgressId = document.createAttribute("id");
for (qIndex; qIndex <= lastQuestion; qIndex++) {
queryAllProgressId.value += qIndex;
queryAllProgress.setAttributeNode(queryAllProgressId);
}
};
.query__all-progress {
width: 0.9rem;
height: 0.9rem;
margin: 0 0.03rem;
border: 1px solid grey;
display: inline-block;
border-radius: 40%;
}
<div class="query__all-progress"></div>
As you can see, I am trying to get the div element by the class name query__all-progress 'cause I need to give it an attribute of id="". And, the value of the id should be from the for loop, which is the qIndex. I tried to do this but it doesn't work. Please help.
I'm just trying to refactor this code guys. Please help:
const renderProgress = () => {
const lastQuestion = 20;
let qIndex = 0;
const queryProgress = document.getElementById("query__progress");
for (qIndex; qIndex <= lastQuestion; qIndex++) {
queryProgress.innerHTML += `<div class='query__all-progress' id="${qIndex}"></div>`;
}
};
You can try to solve it like this:
In your .html file create a element to serve as a container
<div id="container"></div>
I modified your function a bit like this:
const renderProgress = () => {
// COUNTING VARIABLES
let qIndex = 0;
const lastQuestion = 20
// TO STORE EACH ELEMENT
let querys = '';
// PROCESS
for (qIndex; qIndex <= lastQuestion; qIndex++) {
querys += '<div class="query__all-progress" id="'+ qIndex +'"></div>';
}
// INJECTING GENERATED ELEMENTS TO CONTAINER
document.getElementById('container').insertAdjacentHTML('afterbegin', querys);
}
renderProgress();
.css stays the same
.query__all-progress {
width: 0.9rem;
height: 0.9rem;
margin: 0 0.03rem;
border: 1px solid grey;
display: inline-block;
border-radius: 40%;
}
You should have something like this:
And in the inspector:
I hope it helps you.

How to display the arrays in a Textarea element

I want to show the very hard array and hard array in the textarea. Right now, it shows under the textarea as I don't know how to show it in the textarea. The user gives the input and the server response with the hard and very hard sentences from the user input. The hard sentences have a yellow background and the very hard have red background. For now, only the hard and very hard sentences with yellow and red background respectively is shown below the textarea and not the whole thing but I think it isn't intuitive as the user would have to go and search for the sentences in the textarea again as where the sentence exactly lies. So I want the whole thing to be shown in the textarea itself with the hard and very hard sentences highlighted in yellow and red background.
Right now my code looks something like this:
state={
hardArray: [],
vhardArray: []
}
performHard = async () => {
const { enteredText } = this.state;
const body = { text: enteredText };
const stringifiedBody = JSON.stringify(body);
const options = {
method: "POST",
headers: {
"Content-Type": "application/json",
Accept: "application/json"
},
body: stringifiedBody
};
const url = "api/same";
try {
const response = await fetch(url, options);
const result = await response.json();
this.setState(prevState => ({
hardArray: [...prevState.hardArray, ...result.hard]
}));
} catch (error) {
console.error("error");
}
};
performVHard = async () => {
const { enteredText } = this.state;
const body = { text: enteredText };
const stringifiedBody = JSON.stringify(body);
const options = {
method: "POST",
headers: {
"Content-Type": "application/json",
Accept: "application/json"
},
body: stringifiedBody
};
const url ="api/same";
try {
const response = await fetch(url, options);
const result = await response.json();
this.setState(prevState => ({
vhardArray: [...prevState.vhardArray, ...result.very_hard]
}));
} catch (error) {
console.error("error");
}
};
performAnalysis = () => {
this.performHard();
this.performVHard();
};
<textarea
name="enteredText"
className="textareaclass"
placeholder="Enter your text here"
onChange={this.handleChange}
value={enteredText}
></textarea>
<Button
className="rectangle-3"
onClick={this.performAnalysis}>Analyse
</Button>
<div>
{this.state.hardArray.map((word, i) => (
<span className="hardColor">{word}</span>
))}
{this.state.vhardArray.map((word, i) => (
<span className="vhardColor">{word}</span>
))}
</div>
edit: this is how I receive the respond from the server
{
"hard": [
"It's the possibility of having a dream come true that makes life interesting",
"I cannot fix on the hour, or the spot, or the look or the words, which laid the foundation.",
]
"very_hard": [
“He stepped down, trying not to look long at her, as if she were the sun, yet he saw her, like the sun, even
without looking.”
]
}
I want to show all the text in the same textarea where the user wrote his content instead of showing anywhere else in the browser as it will make everything look ugly.
You can only give a textarea one background color, but you can make it transparent and put things behind it to add some color, yea this is a total hack and you will need to fiddle with the sizes and the blank lines to move the text down a bit - I will leave that exercise to you.
This also does not show how to get your values into the textarea but that is simple JavaScript/react code perhaps.
I altered this with some functions to illustrate where you MIGHT simply add/remove blank lines in the textarea to match the height of the background color - would probably have to adjust that background to match when this overflows the size, OR you might adjust the background to make it smaller for the colors.
I will leave it to you to determine which is the better option, I used "|" and "||" as the line/section separators as once it is in the textarea and edited you will need something like that.
All I have time for right now to enhance this but should give a starting point for this somewhat edge case without a clear standard solution.

How to create a ludo board dynamically using Javascript

I am making a board game ludo. I contains four players. The board of ludo looks something like
I have managed to create some part of it dynamically using Javascript.
const qs = str => document.querySelector(str);
const qsa = str => document.querySelectorAll(str);
const ce = (str, props) => {
let elm = document.createElement(str);
if(props){
for(let k in props){
elm[k] = props[k]
}
}
return elm;
}
let main = qs('#main');
function createDiv(type, color){
let div = ce('div');
div.style.backgroundColor = color;
div.style.display = type;
}
let game = Array(52).fill(0);
function createPlayer(color,angle){
let div = ce('div', {className: 'player-cont'})
let table = ce('table');
div.style.transform = `rotate(${angle}deg)`
function createRow(len,colorsSet){
const tr = ce('tr',{className:'tile-row'});
[...Array(len)].forEach((x,i) =>{
let elm = ce('td', {className:'tile'});
if(colorsSet.has(i)){
elm.style.backgroundColor = color;
}
tr.appendChild(elm)
})
return tr;
}
function createBase(){
const base = ce('table', {className: 'base'});
[...Array(2)].forEach(x => {
let row = ce('tr', {className: 'base-row'});
[...Array(2)].forEach(a => {
let td = ce('td', {className: 'base-tile'})
row.appendChild(td);
})
base.appendChild(row)
})
return base;
}
let colorSets = [
new Set(),
new Set([0,1,2,3,4]),
new Set([4])
]
colorSets.forEach(x => {
table.appendChild(createRow(6, x))
})
div.appendChild(table);
div.appendChild(createBase());
return div;
}
let colors = ['red','blue','green','pink'];
colors.forEach((x, i) => {
main.appendChild(createPlayer(x, (i * 90) - 180));
})
.tile {
height: 50px;
width: 50px;
background: orange;
border: 1px solid black;
display: inline-block;
}
table.base td {
height: 50px;
background: orange;
width: 50px;
border-radius: 100px;
}
.player-cont {
background: aliceblue;
width: fit-content;
}
<div id = "main"></div>
But now I am not sure how will I finish this up. You can ignore two things in the above image:
The big border of the of big square of different colors. I just need a single color throughout.
You can ignore the colorful triangles in center. I just need a one color box instead of that.

Delete button works only for last item

I just started working with Javascript and I am trying to make my first "Todo App".
The problem is, that my delete button which should be related to specific div is deleting only last div.
To better understaing check out my code on Codepen:
https://codepen.io/anon/pen/QVPxmG
or here:
var books = ["Bang-1","Bang-2","Bang-3","Bang-4"];
var wrapper = document.querySelector(".wrapper");
var element_div = document.querySelector(".element_div");
var load_button = document.querySelector(".load");
load_button.addEventListener("click", function(){
for(var x=0;x<books.length;x++){
var div = document.createElement("div");
div.setAttribute("class","element_div " + "element_div"+x);
wrapper.appendChild(div);
var element = document.createElement("p");
div.appendChild(element);
element.setAttribute("class", "element"+x);
element.innerHTML = books[x];
var del = document.createElement("button");
del.setAttribute("class", "delete"+x);
div.appendChild(del);
del.innerHTML = 'Delete';
del.addEventListener("click", function(){
div.remove();
},false);
}
},false);
var clear = document.querySelector(".clear");
clear.addEventListener("click", function(){
wrapper.innerHTML = "";
},false);
What Should I change to delete proper div?
Thanks, Mike.
The problem in your case come because of closure,you have declared all your variables using var which will belong to the functional scope and hence when you click on delete, the div that is deleted is the last div since that is what div variable points to after the for loop iteration.
Changing everything to let will work, since let is block scoped and the declaration will be limited to within the for loop
for(let x=0;x<books.length;x++){
let div = document.createElement("div");
div.setAttribute("class","element_div " + "element_div"+x);
wrapper.appendChild(div);
let element = document.createElement("p");
div.appendChild(element);
element.setAttribute("class", "element"+x);
element.innerHTML = books[x];
let del = document.createElement("button");
del.setAttribute("class", "delete"+x);
div.appendChild(del);
del.innerHTML = 'Delete';
del.addEventListener("click", function(){
div.remove();
},false);
}
},false);
Working codepen
You have to use "this" instead of "div" in click event. Something like this:
this.parentElement.remove();
div will have the content after for loop ends. You should capture the correct div for every iteration like below, using pure javascript's immediately invoking function
var books = ["Bang-1", "Bang-2", "Bang-3", "Bang-4"];
var wrapper = document.querySelector(".wrapper");
var load_button = document.querySelector(".load");
load_button.addEventListener("click", function() {
for (var x = 0; x < books.length; x++) {
var div = document.createElement("div");
(function(div) { // Immediately invoking function - IIFE
div.setAttribute("class", "element_div " + "element_div" + x);
wrapper.appendChild(div);
var element = document.createElement("p");
div.appendChild(element);
element.setAttribute("class", "element" + x);
element.innerHTML = books[x];
var del = document.createElement("button");
del.setAttribute("class", "delete" + x);
div.appendChild(del);
del.innerHTML = 'Delete';
del.addEventListener("click", function() {
div.remove();
}, false);
})(div);
}
}, false);
var clear = document.querySelector(".clear");
clear.addEventListener("click", function() {
wrapper.innerHTML = "";
}, false);
